Demonstration of $100\text{Gb}/\mathrm{s}/\lambda\ 32\text{QAM}$-DMT Transmission in Intra-DCI Using 10G-calss EML Modulator and 4-bit DAC

Enabled by fast-precoding DFT -S for P APR suppression and noise-shaping technique for redistribution of quantization-noise in signal quantization with 4-bit DAC, a low-cost 100Gb/s short-haul Intra-DCI using 10G-class EML modulator and 4-bit DAC is experimentally demonstrated in this paper.
